A wheel with a 3-m radius rotates on a stationary axle with constant angular velocity omega= 2 rad/s. During 1 second, what is the distance traveled by a point on the outer edge of the wheel?
a. 2m
b. 6m
c. 3m
d. 9m

Respuesta :

Answer:

b. 6m

Explanation:

A wheel with an angular velocity of 2 rad/s would have swept an angle of 2 rad in 1 second. Since it has a 3m radius, the chord length that it would have swept in an angle of 2 radians is 2 * 3 = 6m, which is also the distance traveled by the wheel, or the point on the outer edge of the wheel.

b. 6m
